Additional context
The reason why this issue exists:

• Input props are being generated by the downshift helper and passed to the AutoCompleteInput component here
• The props are not individually extracted but are destructured into the restProps prop. This is being sent to the InputSearch component coming from the styleguide here
• The InputSearch does not handle any focus events other then it's own. There is no callback on the onFocus event. https://github.com/vtex/styleguide/blob/master/react/components/InputSearch/index.js#L58
